To alt whom it may concern:

Be it known that I, STEPHEN AG'UST'US HASBRQUCK, a citizen 'of 4the United States, residingin the borough of Manhattamin the city, county, and State of New York, haveinvented certain new and useful Improvements in Regulators for Gaslene or other LikeEn` gines, of which the following is a specification.

My invention consists of an improved mechanism for regulatingthe fuel-supply in gasolene and `other like engines by increasing or diminishing the quantity of explosive mixture supplied to the engine and at the sam'e VJtime preserving the proper proportions of atmospheric air and hydrocarbon vapor. In such engines the fuel supplied` to the cylinder in which the explosion takes place consists of a mixture of atmospheric air and gas or vaporized oil combined in proper proportions, and the power of the engine may be regulated by changing the quantity of the supply.

The object of my inventionis to provide a simple and efficient mechanism Afor regulating the quantity of fuel supplied and at the same time preserving the proper proportion of the ingredients.

My invention is illustratedin the accompanyingdrawingsLshowing so much of the mechanism as is necessary to an understanding thereof. v

Figure 1 is a front elevation of the mechanism. Fig. 2 is across-section thereof through the plane X Y of Fig. 1. Fig. 3 is a detailed View of part of the regulating mechanism. Fig. 4 is a perspective View of the air-valve. Fig. 5 is a view in cross-section of a simplifled modification of the mechanism shown in Fig. 2. Figs. 6 and 7 show modied forms of the lever 9 and its connections.

Similar letters and numbers refer to similar parts in the several views.

A is a chamber containing the gasolene or other liquid hydrocarbon, which isvadmitted by the pipe B and kept at a constant level by the overliow-pipe C or other suitable means. The pipe B is connected with the main source of fuel-supply by a feed-pump or other suitable means. The liquid fuel passesfrom ,the chamber A through the aperture D to the needle-valve l. This needle-valve is free to move longitudinally through the sleeve or regulating-screw 2 and is` provided with a pipe l2.

yshoulder 23,'wl1ichengages with the lower ex'- tremity of such regulating-screw. The screw 2 is in screw-threaded' engagement with the casing'of thechaniber, as indicatedin the drawings, and when adjusted to the desired position may be locked inplace by the set-` screw 3. An expansion-spring 4, between the upper end of the screw 2 andthe -head 24e of the needle-valve 1, tends to raise the valve and holds the shoulder 23 in engagement with the lower end of screw 2.

5 is a rotary air-valve provided with a plurality ofr suitable apertures set upon a stationaryseat 7 of similar construction and provided with corresponding apertures and operated bya shaft 6, which'is in turn actuated by a crank 8, provided with a link 13, attached thereto by a pin 14. This crankv may be connected with the governor of the engine t or simply turned when desired by the opera- 16, and the lower extremity of which is in contact `with or close juxtaposition to the head -24 of the needle-valve when the lever is in its normal position.

the pipe 12 with theadmission-valve of the cylinder and` divided by a screen or partition ll, ofwire-gauze or other suitable material, placed directly under the aperture 25, leading downward from the needle-valve 1. The air, entering Aby the air-Valve 5 7, passes through the screen l1, over which the gasolene or other liquid fuel flows after leaving the needle-valve 1, and takes up the liquid fuel in the form of vapor, thus producing the explosive mixture, which is transmitted to the admission-valve of the cylinder bythe There are, however, otherforms of vaporizer which may be used in conjunction IOC with my invention, and I do not limit myself to the particular form of vaporizer` herein p shown and described.

In the simplified modification of myinven- VIo tion shown in Fig. 5 the regulating-screw-2y and the adjusting device 16 are dispensed with and the lever 9 impinges directly upon` the head 24 of theVneedle-valve 1. The adjustment is supplied by the turnbu-ckle 26.- and lock-nuts 27 27, with which the connecting-rod 10 is provided, whereby suchconnecting-rod may be made longer or shorter as required,1or any other convenient means of A regulating the length of such connecting-rod may be used. The spring 4 serves to restore the valve to its normal position 3v but this may i be accomplished by anyother-suitable mechani'sm`as, for example, bysu-itablyattaching vthe head 24 of the valve to the lever 9, so that the lever itself will raise the valve. Twoconvenient devices Vfflrsulch adjustment are illustrated by Figs, 6 and 7. In Fig. 6 the neces- `sary play is ysecured by the slot 28. In Fig.

7 a toggle 29 is substituted for the support 22 for the samepur'pose.

The method of operation of the mechanism is as follows: When theengine is running at full speed, -the air-valve is open to its farthest extent, and the needle-valve after having been adjusted in the proper position by by the. operator or by the governor of theengine or by other convenient means, as hereinbeforesuggested. ,The same motion, acting lupon the connecting-rodlO, draws down the lever 9which by means of the screw 15` depress'es the j needle-valve 1 and so reduces the Supply 0f gasolene or other fuel fed through the valve,` To increase the power, the above-described operation is reversed. The link 13 is brought back to its original position, thus turning the crank 8, revolving the shaft .6, and reopening the `airvalve,and at the Sametime raising the lever 9, and thusreleasing the needle-valve, which is brought backl to its original position by meansof the spring 4r. Any excess of 'gasolene falling to thebottom of `thevaporizing-chamber is carried off bythe overflow-pipe 17. 4

The screw 2-l serves the purpose of xin'g thenormal position of the needle-valve and so regulating'v the amount of gasolene to be admitted when, the `air-valveis open to its farthestextent, and while useful to prevent waste of Afuelsis not essential totheoperation `of the engine. The screw 15 furnishes a con- *venient means of adjusting and regulating l the action of thelever 9 upon the head of the` 6s the lever' may be constructed so' asxto i`mpings rdirectly on the head of the valve, as"

shown in the modification illustrated Fig.

5, in which any necessary adjustment is effected by regulating the length of the connecting-rod l0,or the lever may be connected with the head of the valve-stem and the spring dispensed with, as shown in Figs. 6 and 7. s
